Application filed September 28, 1904. Serial No. 226,345.

To all 10710111, it may concern.-

Be it known that I, JOHN T. DUFF, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented anew and useful Improvement in Gong Attachments; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to street-car gongs and bells, and more especially to the'manner of mounting the same.

The object of my invention is to provide a mounting and ringing attachment for such gongs which is simple of construct-ion, light,

. cheap to manufacture, which can be quickly and easily put in place or removed and without the necessity of using tools for this purpose, and which will securely hold the gong and its ringing means in place.

In the accompanying drawings, Figure 1 is a vertical sectional view of my invention applied to a foot-operated gong, the section being taken on the line 1 1, Fig. 2. Fig. 2 is an inverted plan view thereof, a portion being broken away. Fig. 3 is a section similar to Fig. 1, showing the invention applied to an overhead or elevated gong, the section being taken on the line 3 3, Fig. 4; and Fig. 4 is a bottom plan view of the same.

In the drawings the car-floor or other supporting structure is shown at 1 and the gong at 2. This may be of any known or desired form. The gong is provided with a central unthreaded opening 3, adapted to slip over the supporting stud or bearing 4. The latter is adapted to pass through a suitable opening in the floor or other supporting structure and is provided at its upper end with a circular flange or head 5, provided with prongs 6,.

adapted to take into the floor or other supporting structure to prevent it from turning. At its lower end this support is threaded in order to receive a nut 7 for securing the gong in place. Formed integral with this nut is a suitable support for the pivot of the gong hammer or tapper 8. As shown in the drawings the nut is provided on one side with the projecting perforated ears 9, between which lies the hammer-lever 10, said lever being pivoted in said cars by means of a pin 11.

When the gong is adapted to be operated by foot-power, the bearing or stud 4 will be placed in the floor of the car-vestibule or the like, and it will be made hollow from end to end. The gong will be clamped between the nut 7 and a suitable washer 12, placed between said gong and the car-floor. The hammer-lever 10 will be extended inwardly and have its inner end lying underneath the opening in the bearing 4. Extending through the opening in said bearing is an actuating-pin 13, having a free sliding fit in said opening and being provided at its upper end with a head 14 for operation by the foot of the motorman. This stud will be of such length that when in its normal or elevated position, as shown in Fig. 1,the head 14 will be held some distance above the top of the flange 5 of the bearing 4. The weight of the hammer 8, operating on the long lever 10, will be suflicient to normally keep this pin elevated and the hammer out of contact with the gong. To sound the gong, the motorman will merely press with his foot on the head 14 ofthe pin 13, thus forcing the inner end of the hammerlever 10 downwardly and causing the hammer to strike the gong in the well-understood manner. As soon as the motorman releases the pressure of his foot on the pin 13 gravity will restore the parts to their normal position.

When used for an elevated or overhead gong, the construction shown in Figs. 3 and 4 will be employed. The bearing 4 in this case will be solid and the gong will be held between the nut 7 and a sleeve 12, surrounding the bearing or stud 4 and interposed between the gong and lower face of the roof or other supporting structure 1. The hammer-lever in this case will be provided with a suitable projecting portion 18, to which will be connected a wire, cord, or other suitable means 19 for actuating the same. The operation of this modification will be readily understood from the description and drawings.

In both forms of my invention the support or attachment for the gong is exceedingly simple and light, comprising a suitable headed bearing or stud to which the gong is secured by means of a nut, a suitable spacing washer or sleeve being employed between the gong and the supporting structure. The support for the gong-lever is integral with this nut, so that the parts are reduced to a minimum number and are of an exceedingly simple form. The hammer-lever pivoted to the ears on the nut serves as an arm or lever for turning the nut when putting the gong in place or removing the same. As a consequence no wrench or other tool is necessary. This is a decided advantage.

What I claim is 1. An attachment for gongs consisting of a support adapted to pass through an opening in the supporting structure and provided on one end with a head or flange adapted to bear against said structure, said head being provided with prongs on its lower face, a gong provided with an unthreaded opening passing over said support, a spacing washer or sleeve between said gong and the supporting structure, a collar secured to the end of said support and serving to clamp the gong and spacing member against the supporting structure, and a hammer and lever hinged to said collar.

2. An attachment for gongs consisting of a support adapted to pass through an opening in the supporting structure and provided on one end with a head or flange adapted to bear against said supporting structure and having its other end threaded, a gong provided with an unthreaded opening passing over said support, a spacing member between said gong and the supporting structure, a nut fitting on the threaded end of the support and serving to clamp the gong and spacing member against the supporting structure, and a hammer-lever hinged to said nut.

3. An attachment for gongs consisting of a hollow support adapted to pass through an opening in the supporting structure and provided on one end with a head or flange adapted to bear against said structure, a gong provided with an unthreaded opening passing over said support, a spacing member between said gong and supporting structure, a collar secured to the end of said support and serving to clamp the gong and spacing member against the supporting structure, a hammerlever hinged to said collar,and operating means for said hammer passing through the opening in said support.

4:. An attachment for foot-gongs comprising a hollow support adapted to pass through an opening in the supporting structure and provided on one end with a head or flange adapted to bear against said structure and having its opposite end threaded, a gong provided with an unthreaded opening passing over said support, a nut fitting on the threaded end of said support and serving to clamp the gong against the supporting structure, a hammer lever hinged to said nut, and a pin having a sliding fit in the hollow support and arranged to contact with the hammer-lever.

5. An attachment for foot-gongs com prising a hollow bushing adapted to pass through the supporting structure and having a head or flange at its upper end bearing against said structure and having its lower end threaded, a gong provided with an unthreaded opening passing over said support, a spacing member between said gong and supporting structure, a nut fitting on the threaded end of said support and serving to clamp the gong and spacing member against the supporting structure, said nut being provided with ears, a hammerlever hinged to said ears and having its end extending opposite the opening in the hollow support, and a pin having a sliding fit in said hollow support and arranged to contact with the end of said hammer-lever.

In testimony whereof I, the said J OI-IN T. DUFF, have hereunto set my hand.
